The Master Effects Super Two Hundred is a bass preamp pedal based on the vintage Orange AD200 bass amplifier. It puts the amp's gain and three-band EQ on a pedalboard, so a bassist can dial in that preamp voicing through any amp, cab or direct rig. Master Effects describes it as "our interpretation of the vintage Orange AD200 bass amplifier"1.
The controls
The pedal covers the basics of a bass preamp in six knobs: gain to set how hard the circuit is driven, volume for overall level, a master control, and bass, middle and treble for the three-band EQ. Master Effects lists the controls as "Gain, Volume, Master, Bass, Middle and Treble"1.
| Control | What it does |
|---|---|
| Gain | Sets the amount of drive into the preamp circuit |
| Volume | Sets the pedal's output level |
| Master | A separate master level control |
| Bass | Low EQ band |
| Middle | Mid EQ band |
| Treble | High EQ band |
Where it came from
The Super Two Hundred is a sibling to the Master Effects Super Three Hundred. Master Effects says it "used what we learned from the Super 300 design" and "implemented those opamp topologies to reproduce the sound of the AD200"1. The maker's range also includes the Super Eight Hundred Plus, the Thespian Valve Preamp and the Manta Ray 2-Band and Manta Ray 3-Band, alongside other bass pedals and preamp pedals.
Build, power and buying details
The circuit sits on a professional high quality FR4 PCB in a 125B sized pedal enclosure, and switching is handled by a soft touch relay true bypass circuit1. Power comes from a standard Boss-style 9V/100mA supply1.
Orders typically ship within 2 to 4 weeks, so the pedal is built to order rather than stocked off the shelf1.
The price is $199US plus shipping. Shipping within Canada and the US is $20US, and shipping to the UK, Western Europe, Australia and Japan is approximately $60US. Customers outside Canada are responsible for any customs, import or VAT charges their country levies on the pedal1.
Each pedal comes with a 1 year warranty on parts and labor, which excludes damage from an improper power supply or misuse1.
On sound, Master Effects says the end result is "high quality pedals that sound amazing and are consistent from pedal-to-pedal"1.

Questions
What amp is the Master Effects Super Two Hundred based on?
It is based on the vintage Orange AD200 bass amplifier. Master Effects used opamp topologies developed for its Super 300 design and applied them to reproduce the sound of the AD200 in pedal form.
Is the Super Two Hundred true bypass?
Yes. The pedal uses soft touch relay true bypass switching, so when it is off your bass signal passes through without going through the preamp circuit.
Where is the Master Effects Super Two Hundred made?
Master Effects assembles the Super Two Hundred by hand in Calgary, Alberta, Canada, using a professional high quality FR4 PCB in a 125B sized enclosure.
What power supply does the Super Two Hundred need?
It runs on a standard Boss-style 9V power supply rated at 100mA. Use a supply that meets that rating rather than a low-current daisy-chain output.
What warranty does the Super Two Hundred come with?
Each pedal carries a 1 year warranty on parts and labour. The warranty excludes damage from an improper power supply or misuse.
